Ionisation isomers differ by

Last Updated:

This SSC CGL Chemistry question asks: “Ionisation isomers differ by” The correct answer is Ions in solution. Ionisation isomers produce different ions in solution having same molecular formula. Redox questions should identify oxidation as electron loss or increase in oxidation number and reduction as electron gain or decrease in oxidation number. Acid basicity refers to the number of ionisable protons, not simply the number of hydrogen atoms written in a formula. Periodic trends such as atomic size, ionisation energy and electronegativity depend on effective nuclear charge and shielding, so exceptions should be treated carefully.

ASpatial arrangement
BLigand linkage
CIons in solution
DCoordination number
Correct Answer: Ions in solutionYour Answer: C

Explanation

different ions in solution having same molecular formula. Option A (“Spatial arrangement”) is incorrect because it does not satisfy the chemical formula, reaction, periodic trend, numerical relation, oxidation state or definition required by the question. Option B (“Ligand linkage”) is incorrect because it does not satisfy the chemical formula, reaction, periodic trend, numerical relation, oxidation state or definition required by the question. Option D (“Coordination number”) is incorrect because it does not satisfy the chemical formula, reaction, periodic trend, numerical relation, oxidation state or definition required by the question. The answer field, correct index and explanation therefore all identify Ions in solution. Ionisation isomers produce different ions in solution having same molecular formula.

FAQ

SSC CGL Chemistry FAQs

Common questions and clear answers for this topic.

How many chemistry questions typically appear in the SSC CGL exam?

Chemistry usually contributes a handful of questions within the General Awareness section, generally covering basic concepts rather than calculation-heavy problems.

Which chemistry topics are most important for SSC CGL preparation?

Atomic structure, periodic table trends, acids-bases-salts, metals and non-metals, and carbon compounds are the areas that appear most consistently across past papers.

Is NCERT chemistry enough to prepare for SSC CGL?

NCERT textbooks from classes 9 and 10 cover most of the conceptual base needed, though supplementing with general knowledge about everyday chemical compounds helps too.

What is the best way to remember chemical reactions and formulas for SSC CGL?

Linking reactions to real-world examples, like rusting or antacids, makes them easier to recall than memorizing formulas in isolation.

Does the SSC CGL chemistry syllabus overlap with the school board syllabus?

Yes, a large part of the syllabus mirrors class 9 and 10 science, making school-level revision a practical starting point.
